I want to convert my existing proxy server for my home
network to Linux. But every distribution I have used has never
detected both network cards until SuSE 6.3. I can manually get the
card on the LAN to find the DHCP server, and the NT gives it an IP
address, but can never ping that server; if I change it to a static
IP address, it pings the NT server fine. The real problem is I have
a cable modem on the other NIC, on which I have set up DHCPclient.
I have viewed and edited the sbin/init.d/dhclient file to make sure
it has the ifconfig $NETDEV 0.0.0.0 up statement
in it. I have read the FAQ and I still cannot get this to
work. —Stephen Heaton, srheaton@mediaone.net

All recent distributions work more or less the same in regard
to more than one Ethernet card if they are PCI, as they can all be
autodetected easily. You may, however, need to add an alias for
eth1 in /etc/conf.modules. For example, your conf.modules could
look like this:

alias eth0 tulip
alias eth1 eepro100

After that, you simply need to ifconfig each card
in the usual fashion.

Are you sure that Linux does receive a correct IP, netmask
and broadcast from the DHCP server? You should type ifconfig eth0
(or eth1) and compare the info you're getting from DHCP with the
info you're setting by hand.

The last part, I'm not too sure about. I myself haven't had
much luck with SuSE's DHCP client, while Red Hat's dhcp client has
worked better for me with no special configuration required. —Marc

DevOps represents a profound change from the way most IT departments have traditionally worked: from siloed teams and high-anxiety releases to everyone collaborating on uneventful and more frequent releases of higher-quality code. It doesn't matter how large or small an organization is, or even whether it's historically slow moving or risk averse — there are ways to adopt DevOps sanely, and get measurable results in just weeks.
